Ok, I'm gonna try to make this as short as I can:
I am a
tobacco nut. I love tobacco: the way it smells and tastes, yes still now too. But even above tobacco: I am a menthol junky and after sampling so many brands and flavours I found:
Kool NF (RIP). The best cigg there ever WAS!

IMO of course...
by now I'm a total Menthol junky. I didn't even smoke cloves much anymore (which I had always occassionaly smoked Djarum Blacks or Internationals), I wanted that menthol hit and Kool had the hardest most intense menthol hit I've ever tried, and I was smoking 3 pks a day. I was 20 at this time. Non-menthol cigs aren't even worth smoking to me by now at this point b/c even the strongest couldn't provide the TH I could get off a menthol.
I stayed on those till they stopped making them in 2004. (Screw You RJR!)
By then Kool XL Greens were introduced and moved to Blues when they came out b/c they were mentholly-er.
At the end I was smoking a carton a week at $70. I lasted my run thru the NFs, but now they screw with them again: FSC, UGH! Horrible, Blech!
As far as symptoms: I didn't have a cough, but ciggs (tho not cigars or pipe tobacco) always did cause some congestion/mucus in my sinus cavities, but nothing bad. The FSCs? OMGs I've never felt so crappy ever! They were Horrible in every way.
Now I'm hardly congested at all. I have been singing (which the FSCs had temp killed as well) and it's sooooooo much easier now! LOL My voice has been sounding FANTASTIC! And my
sense of smell/taste is much more acute. Cigars taste far better than they ever did and my perfumes! I'm picking up notes I never smelled in them before!
I now vape mostly Cool! I must say, as a menthol junky: This cart in the 36 delivers more menthol hit than my Kool XL Blues (or NF) ever could! Wow, I can feel the tingle much longer after inhaling!

However, the Menthol carts get love from me too b/c they totally remind me of the good ole Kool greens.
I've been enjoying the candy flavours (Vanilla and Cranberry make me drool) too, but I still need that menthol hit.
ETA: I smoked cigarettes for 17 yrs. duh! how did I forget this doh!
